Figure 1(a) shows the powder X-ray diffraction pattern of WP\(_2\) . The data can be fitted quite well by the space group Cmc2\(_1\)  with lattice parameter \(a\)  = 0.3164(2) nm, \(b\)  = 1.184(2) nm, and \(c\)  = 0.4980(2) nm, consistent with previous report.[1]} The average atomic ratio determined by the EDX is W: P = 1: 2. Figure 1(b) shows the temperature dependence of resistivity in WP\(_2\)  in different fields. The residual resistivity ratio (RRR) in the absence of magnetic field is \(\rho (300K)\) /\(\rho (2K)\)  = 279 with \(\rho (2K)\)  = 0.19 \(\mu \Omega \) cm, indicating small defect scattering in the crystal. The metallic resistivity in \(H\)  = 0 can be described by the Bloch-Grüneisen (BG) model:[2]}
\(\rho (T)=\rho _0 + C(\frac{T}{\Theta _D})^5\int _{0}^{\frac{\Theta _D}{T}}\frac{x^5}{(e^x-1)(1-e^{-x})}dx\)
